Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a moisture-proof storage device for grain processing. Background Technology

[0002] Grain processing refers to the process of removing the husk and bran from grains, as well as packaging and shipping them. A moisture-proof storage device for grain processing is a moisture-proof storage device used in the grain processing process.

[0003] In existing technologies, moisture-proof storage devices typically employ ground-level or side-level ventilation. Ventilation methods include self-heating ventilation and mechanical ventilation. Natural ventilation involves opening vents at the top of the storage silo to allow outside air to enter. Mechanical ventilation, on the other hand, forces air into the storage silo using ventilation equipment. While these methods are more efficient than natural ventilation, they share a common drawback: they only ventilate the surface or shallow layer of grain within the storage silo. Grain in the central part of the silo has a smaller contact area with the air and cannot receive sufficient ventilation, thus reducing the storage time of grain in the central part of the silo. Therefore, a moisture-proof storage device for grain processing is needed to address these issues.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

During rotation, the contact area between the dry air and the grains significantly increases, avoiding the problem of deep grains becoming damp and spoiling under traditional ventilation methods. This achieves uniform moisture protection for all grains in the chamber, significantly extending the overall storage time. Compared to the passive method of natural ventilation that relies on the external environment, the active air drying and circulation design can more stably control the humidity inside the chamber, maintaining a dry state even in high external humidity environments, making the moisture-proof effect more reliable.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a moisture-proof storage device for grain processing, comprising:

[0033] Grain moisture-proof storage bin 1 is equipped with a moisture-proof mechanism. It should be noted that this mechanism allows the grain to have a large contact area with the wind and receive adequate ventilation, thereby increasing the storage time of the grain in the middle of the storage bin.

[0034] The moisture-proof mechanism includes a round box 2, an air pump 3, a top box 4, a desiccant container 5, a sealing rod 6, a servo motor 8, a rotating tube 1 9, and a rotating tube 2 10;

[0035] The round box 2 is fixedly installed on the top of the grain moisture-proof storage bin 1, the air pump 3 is fixedly installed on the top of the round box 2, the top box 4 is fixedly connected to the round box 2, the desiccant container 5 is snapped into the top box 4, the sealing rod 6 is slidably installed on the grain moisture-proof storage bin 1, and the servo motor 8 is fixedly installed at the bottom of the grain moisture-proof storage bin 1. It should be noted that the servo motor 8 is controlled by an external PLC controller. By setting the program in advance, the servo motor 8 can be precisely controlled to rotate clockwise and counterclockwise, and the number of rotations can be precisely controlled. This is existing technology and will not be described in detail here.

[0036] The output end of servo motor 8 is fixedly connected to rotor tube 9, and rotor tube 9 is fixedly connected to rotor tube 10.

[0037] With the above structure, the servo motor 8 and air pump 3 are started, and the desiccant container 5 dries the incoming air. Then, the air enters the rotating tube 9 through the round box 2 and is discharged through the air outlet micro-hole on the rotating tube 10. After the servo motor 8 is started, the rotating tube 9 and the rotating tube 10 can rotate, which can make the grain have a larger contact area with the air and fully receive ventilation treatment, thereby increasing the storage time of the grain in the middle of the storage bin.

[0038] Specifically, the moisture-proof mechanism also includes a baffle 7, a round box 11, and a disc 12. The bottom of the baffle 7 is fixedly connected to the sealing rod 6, and the side of the baffle 7 abuts against the desiccant container 5. The round box 11 is fixedly installed on the top inner wall of the grain moisture-proof storage bin 1. The disc 12 is slidably installed inside the round box 11, and the top of the disc 12 is fixedly connected to the sealing rod 6. The rotating tube 9 is rotatably installed on the round box 11, the grain moisture-proof storage bin 1, and the round box 2. The outer side of the rotating tube 9 is provided with external threads, and the top of the disc 12 is provided with a screw hole, and the external threads are threadedly connected to the screw hole.

[0039] Through the above structure, such as Figure 4 As shown, the external thread is partially provided. The rotating tube 9, located at the top inside the circular box 11, is not provided. When the rotating tube 9 rotates clockwise, the external thread and the screw hole engage, causing the disc 12 to move upwards. This, in turn, causes the sealing rod 6 to move upwards, exiting the vent hole until the external thread on the rotating tube 9 separates from the screw hole. At this point, when the rotating tube 9 continues to rotate clockwise, the external thread and screw hole remain separated. The disc 12 then stops moving upwards, and the incoming dry air is discharged through the vent hole. After ventilation is complete, the output of the servo motor 8 reverses, causing the external thread to dissipate. The threads and screw holes are reconnected, allowing the disc 12 to move downwards, thus sealing the vent with the sealing rod 6 to prevent external moisture from entering. After the sealing rod 6 is inserted into the vent, there is a certain distance between the disc 12 and the bottom of the box 11. When the desiccant container 5 needs to be replaced later, the output of the servo motor 8 is reversed, causing the disc 12 to continue to move downwards. This allows the sealing rod 6 to move the baffle 7 downwards, separating the baffle 7 from the desiccant container 5. At this point, the desiccant container 5 can be removed for replacement.

[0040] Specifically, multiple air outlet micro-holes are opened on the outside of the second tube 10. It should be noted that this facilitates the discharge of dried air through the air outlet micro-holes.

[0041] Specifically, the top of the grain moisture-proof storage bin 1 has multiple sliding holes, and the sealing rod 6 is slidably installed in the sliding holes. The top of the grain moisture-proof storage bin 1 has multiple air outlets, and the sealing rod 6 is engaged with the air outlets. It should be noted that the air that is allowed to enter is discharged through the air outlets. When ventilation is not required, the sealing rod 6 blocks the air outlets.

[0042] Specifically, the top of the rotating tube 9 extends into the circular box 2, and the air pump 3 is fixedly equipped with tube body 1 and tube body 2, which extend into the circular box 2 and the top box 4 respectively. It should be noted that this is to facilitate the flow of air after drying.

[0043] Specifically, the top box 4 has a locking hole on its side, and the desiccant container 5 is locked in place with the locking hole. It should be noted that the desiccant container 5 can be positioned to limit its movement. The desiccant container 5 contains solid caustic soda, which is used to dry the incoming air.

[0044] Specifically, a grain adding pipe 13 is fixedly installed on the grain moisture-proof storage bin 1, and a threaded cap is threadedly connected to the grain adding pipe 13. A stabilizing frame is fixedly installed at the bottom of the grain moisture-proof storage bin 1. A grain discharging pipe 14 is fixedly installed on the grain moisture-proof storage bin 1, and a valve is installed on the grain discharging pipe 14. It should be noted that this facilitates the addition and discharging of grain.

[0045] Working principle:

[0046] S1: When it is necessary to perform moisture-proof ventilation treatment on the grain in the grain moisture-proof storage bin 1, the servo motor 8 and air pump 3 are started first through the external PLC controller. The output end of the servo motor 8 rotates clockwise, driving the first rotating tube 9 and the second rotating tube 10 to rotate clockwise synchronously. Since the external thread on the outside of the first rotating tube 9 is connected to the screw hole at the top of the disc 12, the rotation of the first rotating tube 9 will push the disc 12 to slide upward in the disc 11, thereby driving the sealing rod 6 to move upward along the sliding hole. As the sealing rod 6 moves upward, it gradually separates from the air outlet at the top of the grain moisture-proof storage bin 1. When the external thread on the first rotating tube 9 is completely separated from the screw hole, the disc 12 stops moving upward. At this time, the air outlet is in a fully open state.

[0047] S2: At the same time, the air pump 3 starts to work, drawing outside air into the top box 4 through the second pipe. The desiccant container 5 in the top box 4 contains solid caustic soda. When the air passes through the desiccant container 5, the moisture in it is fully absorbed, achieving air drying. The dried air enters the round box 2 through the connection structure between the top box 4 and the round box 2. Then, the first pipe of the air pump 3 delivers the dried air in the round box 2 to the first rotating pipe 9. The dried air in the first rotating pipe 9 flows into the second rotating pipe 10 along the pipe and is evenly discharged into the grain in the grain moisture-proof storage bin 1 through multiple air outlet micro-holes opened on the outside of the second rotating pipe 10. As the second rotating pipe 10 rotates continuously under the drive of the servo motor 8, the dried air can fully contact the grain in different positions in the storage bin, especially the grain in the center, which greatly increases the contact area between the grain and the dry air, effectively removing the moisture in the grain and achieving comprehensive moisture-proof ventilation.

[0048] S3: During ventilation, the humid air in the chamber is discharged through the air vent at the top, forming an air circulation and further improving the moisture-proof effect. After ventilation is completed, the output of the servo motor 8 is reversed by the PLC controller, and the first rotating tube 9 and the second rotating tube 10 rotate counterclockwise. The external thread is reconnected to the screw hole of the disc 12, which drives the disc 12 and the sealing rod 6 to move down until the sealing rod 6 is re-engaged into the air vent, thus sealing the air vent and preventing external moisture from entering the storage chamber.

[0049] S4: When it is necessary to replace the desiccant container 5, continue to control the output end of the servo motor 8 to reverse, so that the disc 12 moves further down, and the sealing rod 6 drives the baffle 7 to move down synchronously until the baffle 7 is completely separated from the desiccant container 5. At this time, the desiccant container 5 can be taken out from the locking hole of the top box 4, replaced with new desiccant, and then re-locked back into its original position. Then, the baffle 7 is adjusted upward by the servo motor 8 to reset, thereby fixing the desiccant container 5. Through the coordinated operation of the above components, the device can not only fully ventilate and prevent moisture in all grains in the storage bin, but also effectively block the intrusion of external moisture, significantly extending the storage time of grains and meeting the moisture-proof storage requirements in the grain processing process.

Specific embodiments have been used to illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
